Hello,
You may add this line to worpress.css (in ../wp-includes/js/tinymce/wordpress.css)
at line 53 (body.mceContentBody)
body.mceContentBody {
font: 13px/19px Georgia, "Times New Roman", "Bitstream Charter", Times, serif;
padding: 0.6em;
margin: 0;
}
and replace it with
body.mceContentBody {
background-color:#FFF !important;
font: 13px/19px Georgia, "Times New Roman", "Bitstream Charter", Times, serif;
padding: 0.6em;
margin: 0;
}
see this: “background-color:#FFF !important;” !important is for this line to take precedence on the body color of your theme.
